    <p>I have a multivaluefield with a charfield and choicefield. I need to pass choices to the choicefield constructor, however when I try to pass it into my custom multivaluefield I get an error <code>__init__()</code> got an unexpected keyword argument 'choices'. </p> <p>I know the rest of the code works because when I remove the choices keyword argument from <code>__init__</code> and super, the multivaluefield displays correctly but without any choices.</p> <p>This is how I setup my custom multivaluefield:</p> <pre><code>class InputAndChoice(object): def __init__(self, text_val='', choice_val=''): self.text_val=text_val self.choice_val=choice_val class InputAndChoiceWidget(widgets.MultiWidget): def __init__(self, attrs=None): widget = (widgets.TextInput(), widgets.Select() ) super(InputAndChoiceWidget, self).__init__(widget, attrs=attrs) def decompress(self,value): if value: return [value.text_val, value.choice_val] return [None, None] class InputAndChoiceField(forms.MultiValueField): widget = InputAndChoiceWidget def __init__(self, required=True, widget=None, label=None, initial=None, help_text=None, choices=None): field = ( fields.CharField(), fields.ChoiceField(choices=choices), ) super(InputAndChoiceField, self).__init__(fields=field, widget=widget, label=label, initial=initial, help_text=help_text, choices=choices) </code></pre> <p>And I call it like so:</p> <pre><code>input_and_choice = InputAndChoiceField(choices=[(1,'first'),(2,'second')]) </code></pre> <p>So how do I pass the choices to my ChoiceField field?</p> <p>Edit:</p> <p>I've tried stefanw's suggestion but still no luck. I've used logging.debug to print out the contents of InputAndChoiceField at the end of the init and self.fields[1].choices contains the correct values as per above however it doesnt display any choices in the browser.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
